Detailed implementation manners
[0023] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0024] Embodiment 1: A workpiece fixing device for a wire cutting machine tool. Refer to Figure 1 and Figure 2 As shown, it includes a mounting base 1 and a placing table 2. The mounting base 1 is installed on the wire cutting machine tool by means of bolt connection. A placing table 2 for placing workpieces is installed on the mounting base 1 by means of bolt connection. It also includes a first motor 3, a connecting rod assembly 4, a mounting block 5, a special-shaped fixture 501, an auxiliary clamping plate 502, and a guide rod 6. A first motor 3 is installed in the middle of the mounting base 1 by means of bolt connection. The output shaft of the first motor 3 faces upward. A guide rod 6 is fixedly connected to the mounting base 1 by means of bolt connection. Two symmetrical mounting blocks 5 are horizontally slidably arranged on the guide rod 6, and the mounting blocks 5 are slidably arranged in the middle of the top of the placing table 2. A connecting rod assembly 4 for transmission is jointly arranged between the two mounting blocks 5 and the output shaft of the first motor 3. A special-shaped fixture 501 is installed on the mounting block 5 by means of bolt connection. An auxiliary clamping plate 502 is rotatably arranged on the special-shaped fixture 501.
[0025] When wire cutting of a workpiece is required, first place the workpiece on the placement table 2. Then start the first motor 3 to rotate. The output shaft of the first motor 3 drives two mounting blocks 5 to slide along the guide rod 6 towards the side close to each other through the connecting rod assembly 4. When the special-shaped fixture 501 contacts the workpiece, the auxiliary clamping plate 502 rotates along with the workpiece shape until the auxiliary clamping plate 502 fits the surface of the workpiece shape. At this time, the special-shaped fixture 501 clamps and fixes the workpiece. Then turn off the first motor 3 to perform wire cutting on the workpiece; by rotating the first motor 3 in the reverse direction and pushing the two mounting blocks 5 to slide in opposite directions through the connecting rod assembly 4, the special-shaped fixture 501 will release the workpiece, and the workpiece can be taken out.
[0026] Embodiment 2: On the basis of Embodiment 1, refer to Figure 3 As shown, it further includes a first housing 7 installed on the placement table 2 by means of bolt connection. A second motor 8 is installed in the first housing 7 by means of bolt connection. A fan 9 for blowing air is fixedly connected to the output shaft of the second motor 8 by a key. A protective net 10 for blocking foreign objects is embedded at the opening of the first housing 7.
[0027] After the processing is completed, there will be a lot of processing debris remaining on the placement table 2. At this time, start the second motor 8 to drive the fan 9 to rotate. The fan 9 blows air towards the placement table 2 to blow off the debris on the placement table 2 for cleaning, keeping the placement table 2 clean and avoiding unevenness when placing the workpiece, which may affect the subsequent processing of the workpiece.
[0028] Refer to Figure 3 and Figure 4 As shown, it further includes a second housing 11 installed on one side of the mounting seat 1 by means of bolt connection. Two air blowers 13 for suction are installed in the upper part of the second housing 11 by means of bolt connection. An activated carbon filter plate 14 for filtering is installed in the middle part of the second housing 11 by means of bolt connection. An air outlet 15 is connected and communicated with one side of the lower part of the second housing 11. The activated carbon filter plate 14 is located between the air outlet 15 and the air blower 13. A protective fence 12 for filtering foreign objects is installed at the opening of the second housing 11 by means of bolt connection.
[0029] When wire cutting is in progress, pungent odors may be generated, and the volatilization of the cutting fluid may also cause harm to the human body. At this time, start the air blower 13 to draw the air with pungent odors and harmful gases into the second housing 11. The harmful substances in the air are absorbed by the activated carbon filter plate 14 and then discharged outward through the air outlet 15, which is green and low-carbon.
[0030] Refer to Figure 5As shown in the figure, it further includes a protective cover 16 slidably arranged on the edge of the mounting base 1. A mounting frame 17 is mounted on the side of the mounting base 1 by means of bolt connection. A clamping rod 18 is slidably arranged horizontally on the mounting frame 17. Two upper and lower card slots 20 are formed on one side of the protective cover 16. The clamping rod 18 can be clamped in the card slot 20. Three elastic members 19 are wound around the clamping rod 18. The elastic members 19 push the clamping rod 18 to reset and be clamped with the card slot 20.
[0031] When wire cutting the workpiece, in order to avoid the splashing of debris and cutting fluid, by pulling the clamping rod 18 to slide along the mounting frame 17 to the side away from the protective cover 16, at this time the elastic members 19 are compressed and deformed, so that the clamping rod 18 is disengaged from the upper card slot 20 of the protective cover 16. Then pull the protective cover 16 to slide upward along the mounting base 1 to enclose and cover the placing table 2 and the cutting area, and release the clamping rod 18. At this time, the elastic members 19 recover to their original state without force and push the clamping rod 18 to slide back to its position, so that the clamping rod 18 is clamped in the lower card slot 20 of the protective cover 16 to limit and fix the protective cover 16.
[0032] Refer to Figure 2 and Figure 6 As shown in the figure, on the side where the two mounting blocks 5 are close to each other, a telescopic belt 21 is fixedly connected together by means of riveting; a protective shell 22 is mounted on the mounting base 1 by means of bolt connection. The first motor 3 is arranged in the protective shell 22, and the output shaft of the first motor 3 penetrates to the outside of the protective shell 22.
[0033] The telescopic belt 21 expands and contracts as the two mounting blocks 5 move. Through the telescopic belt 21, the debris generated by the workpiece cutting can be supported to avoid the debris falling into the corners that are difficult to clean; the protective shell 22 can protect the first motor 3 to prevent the first motor 3 from being damaged by collision.
[0034] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
